Expert Tip: Varying Taste

This keto smoothie is a very versatile recipe that makes it tops the list of my best keto smoothie recipes.

You can transform it by adding the following ingredients:

  • Raspberries or Strawberries
  • Spinach or Kale – full of nutrients, vitamins, antioxidants, and minerals.
  • Almond Butter – instead of peanut butter. You can also use other nut butter.
  • MCT Oil – while it barely changes the flavor, it boosts the healthy fats in your smoothie.
  • Chia Seeds – to add thickness
  • Vanilla extract or almond extract.
  • Turmeric – for a touch of spices.
  • Fresh Mint, Cucumber, or Celery – for a fresh taste.

Storage Instructions

Keto Smoothies, like regular smoothies, are tricky to store as the various phases in the liquid tend to separate.

However, you can store them in a container with a lid in the refrigerator. Make sure to blend it again for a few seconds before serving to get its full creamy texture back!

Frequently Asked Questions

Let me answer the common questions about this keto smoothie.

Why can’t I use dairy milk in a keto smoothie?

Of all dairy products, milk is one of the highest in carbs.
Milk is therefore not keto-friendly since it contains a large amount of lactose, one of the disaccharides that increase blood sugar levels quickly.

Are You Allowed Smoothies On Keto?

Classic takeaway smoothies are most of the time not keto-friendly. However, keto smoothie recipes like this one are perfectly fine to have daily.

Can I Add Bananas To My Keto Smoothie?

Bananas are not recommended on a keto diet because they are quite high in carbs.
As a result, a very small amount of banana contains as many carbs as many raspberries or strawberries.

Can I Use Another Nut Milk?

You can use any plant based milk such as coconut milk, cashew milk, or almond milk.

Can I Take A Peanut Butter Smoothie As A Protein Shake?

Absolutely! Many Keto-friendly smoothies can be used as protein shakes. Just make sure to include enough good protein sources!
One way to add some healthy, keto-friendly vegetarian proteins is to add a scoop of low-carb protein powder. Most of them would not alter the total carbs but would boost your proteins!

Is Peanut Butter Keto-Friendly?

Yes, you can have peanut butter on a keto diet. Obviously, it has to be pure peanut butter made of 100% peanuts with no added sugar and no added oil.
In fact, vegetable oils are not keto-friendly, and many brands add oils or sugar to their products.
So make sure to check the ingredient list and look for peanuts only or peanuts and salt.
So, is this chocolate peanut butter smoothie keto? Yes, it very much is! Use it to top up your macros!
